Title: Apparatus and method for pulse propagation analysis of a pipeline or the like
Inventor: BURNETT GALE D
IPC: G01M3/40
Filed: 1990-04-26
Granted: 2001-04-03
Abstract: A system for ascertaining the existence and location of anomalies along the length of a member, such as an underground pipeline. Electrical pulses are imparted to the pipeline at opposite ends thereof, with these pulses being synchronized so that they meet at predetermined locations along the length of the pipeline. The wave form of one of the pulses which has passed through the point of intersection is analyzed to determine the possibility of an anomaly being present at the location of intersection. These readings can be correlated to half-cell readings which could be taken along the pipeline as a means of analyzing pipeline conditions.

Abstract: A side web non-pneumatic tire ("SWNPT") is integrally molded from a stiff, resilient elastomeric material with particular specifications, to form a unitary honeycomb structure bounded by integrally molded outer and inner cylindrical coaxial and coextensive members ("hoops"), and, a single side web member. The outer hoop is supported and cushioned by the honeycomb which comprises a plurality of circumferentially spaced apart, angularly oppositely directed planar rib members (ribs) bounded by the side web on one side only. The side web, preferably on the outboard edge of the hoops, connects the hoops near their outboard edges. The opposite side surfaces of the side web lie at an angle .THETA. in the range from 0° to 30° on either side of vertical to the rotational axis of the SWNPT. The ribs extend axially along the inner and outer hoops, connecting them, and the outboard edges of all the ribs lie upon the inboard face of the web. The ribs on each side are angled at opposite angles in the range from 15° to 75° to radial planes which intersect them at their radially inner ends. A rubber tread is secured to the outer surface of the outer hoop. The coaction of the structural elements of the SWNPT provide a load-supporting structure which, in opera-tion, is subjected to continuous compression and tensile forces as it travels over the ground. Deformation and buckling characteristics of the SWNPT are derived from the honeycomb structure of an elastomer which provides the SWNPT with "ride" and "handling" comparable to those of a conventional pneumatic tire. The outer hoop has a vulcan-ized rubber tread secured to the hoop's outer surface to withstand travel over a road surface. The unribbed face of the single side web may be faced with an elastomeric sidewall to resemble the sidewall of a conventional pneu-matic tire.

Abstract: A flexible glass fiber reinforcement material has a microwave-sensitive or ultraviolet sensitive binder added and is formed into a desired shape.  Selected electromagnetic energy (microwave or ultraviolet) is then applied to cure and rigidize the binder.  A mold for shaping the reinforcement material comprises a mold cavity defined by microwave or ultraviolet transparent material divided into separate and separable mold parts and, for microwave applications, each part carries one half of a split microwave waveguide which directs microwave energy to cure the binder resin when the mold is closed.  For ultraviolet applications, an ultraviolet source (or sources) is located in the mold.  Energetic stitching of a reinforcement rib is performed by applying a binder resin to the  rib at at least one location, placing that location into contact with a preform and curing the binder resin to bond the parts together.

Abstract: ABSTRACT           To produce a cathode voltage of a cathode ray tube that provides black level compensation, a secondary winding of a flyback transformer is coupled in series with a resistor, a capacitor and a rectifying diode. During flyback, a voltage pulse is developed across the capacitor at a magnitude that increases when the average value of the beam current increases. The voltage pulse causes the cathode voltage to first decrease when the beam current increases.

Abstract: The invention is directed to a liquid strainer and a  blank for forming the strainer.   The strainer has  a  conical shape  with an apex portion completely surrounded by a  filtering cloth  and  folded  from  the blank  to  exclude  any  unfiltered passageway.   The blank has the general shape of a disk truncated about  two angularly spaced radial sides,  the angle between  the sides  allowing for formation of a conical shape when  the  sides overlap. A   circular  aperture  is  partly  carved   at   the intersection  of  the two sides, the remaining  portion  of  the aperture is surrounded by a ring extending from the  sides.   The aperture is covered by a filtering cloth peripherally adhering to the blank and the ring.  When the blank is folded, the ring forms and  continuously extends from the latter.   The filtering  cloth which  is  glued  to the ring completely  closes  any  passageway through the folded cloth.

Title: Electro-photographic printing apparatus
Inventor: IKEMATSU HIDEKI
IPC: G03G15/20
Filed: 1991-06-19
Granted: 1998-08-18
Abstract: A fixing unit of an electro-photographic apparatus comprises:  a heat roller installed on a frame, for fixing a toner image on a sheet; a pressure roller for pinching the sheet with the heat roller; a separator contacting the heat roller, for separating the sheet from the heat roller; a cleaning wiper contacting the heat roller, for cleaning the heat roller; and a sub-frame carrying the pressure roller, the separator and the cleaning wiper.  The sub-frame is rotatable about an axle which is installed on the frame, in parallel to the heat roller.  The pressure roller, the separator and the cleaning wiper are released all together from the heat roller when the sub-frame is opened by being rotated around the axle.          In the thus-opened state, any jammed sheet can be easily taken out by an operator as the jammed sheet is exposed    in a wide space and the sheet is merely sticking to heat roller without being undesirably snagged by the separator or by the cleaning wiper.  Moreover, the easy sheet-removal operation prevents the operator's fingers from being burnt by touching the hot heat roller.
